Nice to see some other people actually own the now dead Ti-85... =)))
Rant: If you make a demo for the Ti-8x Don't use TI-BASIC. Any monkey with 2cents worth of knowledge could cook up some lame text fx like this. The Ti-85 has a Zilog Z80 Cpu (6mhz) and is a viable "platform" imho, as you can do some pretty neat things with it (Check out some of the stuff Jimmy Mardell and his crew have made). Noice's Ti-83 demos as well are pretty good...
